Tossa jute (Corchorus olitorius L.) is an
important lingo-cellulosic bast fibre-crop. It provides
biodegradable and environment friendly fibre next to cotton,
in terms of usage, global consumption, production, and
availability. Narrow genetic diversity of the crop is the
major hurdle, which is a demand at priority for any crop
improvement programme. In the current investigation 138
jute genotypes of C. olitorius were characterized with ten
jute specific SSR markers. A total of 23 alleles were
amplified with an average of 2.3 alleles per locus and the
PIC value ranged from 0.13 to 0.76 with an average of
0.455. The un-weighted pair-group method with arithmetic
average cluster analysis of the 138 jute genotypes depicted
a dendrogram using DARWIN, which divided the genetic
resource into three major clusters. The study indicated the
utility of SSR primers for providing useful and high levels
of polymorphism for individual plant genotypes even with
a narrow genetic base. Based on cluster analysis the most
divergent genotypes identified were OIJ 167 (from
Indonesia), OIM 058 and OIM 059 (India), however based
on the agronomic traits as maximum plant height, basal
diameter and fibre weight they were OIJ 245, OIJ (153 and
161) and OIJ 040, respectively
